Arbitrary-bandwidth Brillouin slow light in optical fibers

摘要: Brillouin slow light in optical fibers is a promising technique for the development of all-optical buffers to be used routers. The main drawback this up now has been its narrow bandwidth, normally restricted 35 MHz conventional single-mode fibers. In paper we demonstrate experimentally that with an arbitrary large bandwidth can readily obtained using simple and inexpensive pump spectral broadening technique. our experiments, show delaying 2.7 ns pulses over slightly more than one pulse length only some residual (<25%) width. We see no limit extend GHz-bandwidth signals.
